Die Deckschicht kann auch die gesamte Fläche der ersten Hauptseite des Kartenkörpers einnehmen und dabei die aktive Hauptseite der Anzeigeeinrichtung bedecken.In a further embodiment, at least the active Main side of the display device covered by a cover layer. In this case, the cover layer before the introduction the display device in the card body with the active Be connected to the main page. Alternatively, first the display device be placed on the card body and then covered the active main page of the display device become. The topcoat can also cover the entire area take the first major side of the card body and thereby cover the active main page of the display device.

Vorzugsweise ist die Deckschicht fest mit dem Kartenkörper verbunden, während zu der Anzeigeeinrichtung keine feste Verbindung besteht. In der Konsequenz bedeutet dies, daß die Anzeigeeinrichtung mit dem Kartenkörper beispielsweise lediglich im Bereich des ersten und zweiten Kontaktelementes miteinander verbunden ist. Die mechanischen Belastungen, die bei einer Biegebeanspruchung auf die Anzeigeeinrichtung wirken können, sind somit minimal.Preferably, the cover layer is fixed to the card body connected while to the display device no fixed connection consists. As a consequence, this means that the display device For example, with the card body only in the region of the first and second contact elements with each other connected is. The mechanical loads at a bending stress acting on the display device can, are thus minimal.

In einer weiteren Ausgestaltung weist der Kartenkörper eine zweite Ausnehmung auf, deren laterale Abmaße größer als die der ersten Ausnehmung sind und die in etwa denen der Deckschicht entsprechen. Dabei sind die jeweiligen Seitenwände der ersten und zweiten Ausnehmung zur Bildung einer Auflagefläche für die Deckschicht in etwa äquidistant angeordnet. Die erste Ausnehmung weist somit größere laterale Abmaße, jedoch eine geringere Tiefe als die erste Ausnehmung auf. Hierdurch ergibt sich ein im Querschnitt stufenförmiger Verlauf der ersten und zweiten Ausnehmung in dem Kartenkörper. Die zwischen der ersten und der zweiten Ausnehmung gebildete Stufe wird dann dazu benutzt, eine Auflagefläche für die Deckschicht zu bilden. Die Tiefe der zweiten Ausnehmung ist dabei an die Dicke der Deckschicht angepaßt, so daß sich im Ergebnis eine ebene Fläche der ersten Hauptseite der Datenträgeranordnung ergibt.In a further embodiment, the card body has a second recess whose lateral dimensions are larger than the the first recess and the approximately the top layer correspond. Here are the respective side walls the first and second recess to form a support surface arranged approximately equidistantly for the cover layer. The first recess thus has larger lateral dimensions, however a smaller depth than the first recess. hereby results in a cross-sectionally stepped course the first and second recesses in the card body. The formed between the first and the second recess stage is then used to provide a support surface for the cover layer to build. The depth of the second recess is adapted to the thickness of the cover layer, so that in the result a flat surface of the first main page of the disk array results.

Eine weitere Reduzierung der auf die Anzeigeeinrichtung wirkenden Kräfte kann dadurch erzielt werden, daß zwischen der Deckschicht und der aktiven Hauptseite der Anzeigeeinrichtung ein Gleitmittel vorgesehen ist. Vorzugsweise wird auch zwischen der passiven Hauptseite der Anzeigeeinrichtung und dem Boden der ersten Ausnehmung ein Gleitmittel vorgesehen.A further reduction of acting on the display device Forces can be achieved in that between the Cover layer and the main active side of the display device a lubricant is provided. Preferably also between the passive main side of the display device and the Bottom of the first recess provided a lubricant.

Eine bessere Sicht auf die Anzeigeeinrichtung wird dadurch erzielt, daß die Deckschicht als Polarisator ausgebildet ist.A better view of the display device is thereby achieved that the cover layer is formed as a polarizer.

Die feste Verbindung zwischen der Anzeigeeinrichtung und dem Kartenkörper wird vorzugsweise durch einen Leitkleber hergestellt.The fixed connection between the display device and the Card body is preferably made by a conductive adhesive.

Die Erfindung wird anhand der nachfolgenden Ausführungsbeispiele näher erläutert. Es zeigen:

Im folgenden werden gleiche Bezugszeichen für gleiche Elemente verwendet.In the following, the same reference numerals for the same elements used.

In der Figur 1 ist ein erstes Ausführungsbeispiel der erfindungsgemäßen Datenträgeranordnung dargestellt. Auf einer ersten Hauptseite 11 eines Kartenkörpers 10 ist eine erste Ausnehmung 15 vorgesehen. In dieser ist eine an die Abmaße der ersten Ausnehmung 15 angepaßte Anzeigeeinrichtung 20 gelegen. Auf einer passiven Hauptseite 22 weist die Anzeigeeinrichtung 20 ein zweites Kontaktelement 23 auf, das mit einem an entsprechender Stelle gelegenen ersten Kontaktelement 13 des Kartenkörpers 10 mechanisch und elektrisch über einen Kleber 30 verbunden ist. Als Kleber wird vorzugsweise ein Leitkleber verwendet, der auch den elektrischen Kontakt zwischen dem ersten und dem zweiten Kontaktelement sicherstellt. Die Verbindung 31, die durch das erste und zweite Kontaktelement gebildet ist, stellt den einzigen festen Kontakt zwischen der Anzeigeeinrichtung 20 und dem Kartenkörper 10 dar. Das heißt, der restliche Bereich der passiven Hauptseite ist gegenüber dem Boden 18 der Ausnehmung 15 verschiebbar. Eine Verschiebung könnte sich beispielsweise durch eine Durchbiegung des Kartenkörpers ergeben.In the figure 1 is a first embodiment of the invention Disk arrangement shown. On a first Main side 11 of a card body 10 is a first recess 15 provided. In this one is to the dimensions of the first recess 15 adapted display device 20 located. On a passive main page 22, the display device 20, a second contact element 23, which with a corresponding to Positioned first contact element 13 of the Card body 10 mechanically and electrically via an adhesive 30 is connected. As an adhesive is preferably a conductive adhesive which also uses the electrical contact between the first and the second contact element ensures. The connection 31 formed by the first and second contact members is the only firm contact between the display device 20 and the card body 10 is. That is, the remaining area of the passive main page is opposite the bottom 18 of the recess 15 slidably. A shift could, for example, by a deflection of the Map body revealed.

Die aktive Hauptseite 21 der Anzeigeeinrichtung 20 wird durch eine Deckschicht 14 geschützt. Die Deckschicht 14 und die Anzeigeeinrichtung 20 haben gemäß den Gedanken der Erfindung keinen Bereich, an dem eine feste Verbindung zueinander besteht. Die Deckschicht 14 ist aus diesem Grund mit dem Kartenkörper 10 fest verbunden. Der Kartenkörper 10 weist zu diesem Zweck eine zweite Ausnehmung 16 auf, die, wie in dem Querschnitt gut ersichtlich ist, etwas größere laterale Abmaße als die erste Ausnehmung 15 aufweist. Hierdurch entsteht ein im Querschnitt stufenförmiger Verlauf. Die Deckschicht 14, die in ihrer Dicke an die Tiefe der zweiten Ausnehmung 16 angepaßt ist, um eine ebene Oberfläche auf der ersten Hauptseite 11 zu erzielen, liegt somit auf Auflagebereichen 32 auf und ist mit diesen und gegebenenfalls mit der Seitenwand 19 zum Beispiel über einen Kleber fest verbunden.The active main page 21 of the display device 20 is through a cover layer 14 protected. The cover layer 14 and the display device 20 have according to the idea of the invention no area where there is a fixed connection to each other. The cover layer 14 is for this reason with the card body 10 firmly connected. The card body 10 is facing For this purpose, a second recess 16 which, as in the Cross-section is clearly visible, slightly larger lateral dimensions as the first recess 15 has. This results a step-shaped profile in cross-section. The cover layer 14, in their thickness to the depth of the second recess 16 is adapted to a flat surface on the first main page 11 to achieve is thus on support areas 32 and is with these and optionally with the side wall 19th For example, firmly connected via an adhesive.

Zur Reduzierung von Quer- und Scherkräften, die bei einer Durchbiegung auftreten können, wird vorteilhafterweise zwischen der Unterseite der Deckschicht 14 und der aktiven Hauptseite 21 sowie zwischen dem Boden 18 und der passiven Hauptseite ein Gleitfilm eingebracht. Dieses Gleitmittel kann beispielsweise ein Silikon-Öl sein.To reduce lateral and shear forces in a Deflection can occur, advantageously between the underside of the cover layer 14 and the active Main page 21 as well as between the floor 18 and the passive Main side introduced a sliding film. This lubricant can for example, be a silicone oil.

Durch die feste Verbindung zwischen der Deckschicht 14 mit dem Kartenkörper 10 wird eine hermetische Versiegelung der ersten Ausnehmung erzielt. Die Deckschicht 14 ist vorzugsweise als Polarisator ausgeführt, der einerseits eventuell entstehende Schmelzmarkierungen im Bereich der Verbindung 31 abdecken kann und andererseits die Ablesbarkeit der Anzeigeeinrichtung erhöht.Due to the firm connection between the cover layer 14 with The card body 10 is a hermetic seal of the achieved first recess. The cover layer 14 is preferably designed as a polarizer, on the one hand possibly arising Cover melting marks in the area of compound 31 can and on the other hand, the readability of the display device elevated.

In der Figur 1 ist die Verbindung 31, die aus dem ersten und dem zweiten Kontaktelement 13, 23 gebildet ist, in einem Randbereich des Bodens 18 der ersten Ausnehmung 15 gelegen. Diese Ausgestaltung ermöglicht eine besonders gute Reduzierung von Scherkräften. Wie aus der Figur 2 ersichtlich ist, kann die Verbindung 31 im gesamten Bereich der passiven Hauptseite 22 der Anzeigeeinrichtung gelegen sein. Gegenüber den aus dem Stand der Technik bekannten Anordnungen wird in jedem Fall eine Streßreduzierung auf die Anzeigeeinrichtung erzielt.In the figure 1, the compound 31, consisting of the first and the second contact element 13, 23 is formed in one Edge region of the bottom 18 of the first recess 15 located. This embodiment allows a particularly good reduction of shear forces. As can be seen from FIG. 2, can compound 31 in the entire range of passive Main page 22 of the display device may be located. Across from the arrangements known from the prior art is in In any case, a stress reduction on the display device achieved.

Das zweite Ausführungsbeispiel gemäß der vorliegenden Figur 2 unterscheidet sich von dem ersten Ausführungsbeispiel weiterhin dadurch, daß der Kartenkörper 10 lediglich eine erste Ausnehmung 15 aufweist. Dadurch, daß die Deckschicht 14 auf die gesamte Hauptseite 11 des Kartenkörpers aufgebracht ist, besteht keine Notwendigkeit, eine zweite Ausnehmung vorzusehen, die eine Auflagefläche für die Deckschicht bildet. Die zweite Variante ermöglicht eine besonders ebene Oberfläche der erfindungsgemäßen Datenträgeranordnung.The second embodiment according to the present Figure 2 differs from the first embodiment further in that the card body 10 only a first Recess 15 has. Characterized in that the cover layer 14 on the entire main side 11 of the card body is applied, there is no need to provide a second recess, which forms a bearing surface for the cover layer. The second variant allows a particularly flat surface the data carrier arrangement according to the invention.

Die Erfindung ermöglicht eine Datenträgeranordnung, bei dem die Anzeigeeinrichtung nur in einem Teilbereich fest mit dem Kartenkörper verbunden ist. Es erfolgt somit keine flächige Verbindung der Anzeigeeinrichtung mit dem Kartenkörper. Demzufolge ist die Anzeigeeinrichtung gleitfähig gegenüber dem Kartenkörper sowie einer gegebenenfalls vorhandenen Deckschicht. Hierdurch lassen sich auf die Anzeigeeinrichtung wirkende Belastungen, zum Beispiel durch eine Durchbiegung, stark verringern. The invention enables a data carrier arrangement in which the display device only in a partial area fixed to the Card body is connected. There is thus no areal Connection of the display device with the card body. As a result, the display device is slidable with respect to Card body and any existing cover layer. This allows the display device acting loads, for example by a deflection, greatly reduce.
